COMBINED STREET-RECEIVER AND STENCH-TRAP.

SPECIFICATION forming part of Lettels Patent No. 329,404, dated October 27, 1885.

Application filed April 8, 1585. Serial No. 161,631. (No model.)

To all whom it may concern.-

Be it known that I, DAVID W. MoCoNNELL, of Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Combined Street-Receiver and Stench'rap, of which the following is a specification.

My invention relates to an improvement in combined street-receivers and stench-traps; and it has for its object the production of a trap to which ready access can be had for the purpose of cleaning it from deposits of solid matter, and which will prevent the escape of obnoxious gases from the sewer with which it is connected.

With these ends in view my invention consists of the improvements which will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure l is a longitudinal sectional elevation of my improved street-receiver and stenchtrap. Fig. 2 is a vertical crosssection on line a" .fr of Fig. l, and at right angles thereto. Figs. 3 and 4 are horizontal sections on lines y y and z z of Fig. l, respectively. Fig. 5 is a fragment-ary horizontal section of one of the side walls of the trap, and Fig. 6 a similar view, on an enlarged scale, of the front wall. Fig. 7 is a front elevation of the hinged plate of the trap.

Like letters of reference denote like parts in the several figures.

A represents the sewer, and B the street receiver, composed of a four-sided box having a half-round bottom, b.

C is the removable cover, resting on the top of the receiver, and provided with a grate, c, through which the water enters the receiver.

d d represent, respectively, the perpendicular front and rear walls of the receiver B 5 and di represent the inclined side walls thereof.

E represents a curved shield or plate, which is hinged at its upper edge to the front wall, d, at e, and extends backwardly and downwardly to about the center of the receiver and below the opening of the sewer or drain pipe A. This shield or plate extends across the receiver B from side to side thereof, and conforms to the form of the side walls, d2. The sides of the shield or plate E rest upon downwardly-curved ledges F, formed on the side walls, d2, of the receiver. These ledges are curved in cross-section, so as to form on their rear sides depressions or channels, which receive packings g of lead pipe. The plate E is provided along its sides with ribs h, which impinge against the tubular packings g when the plate E is closed down upon its seat, thereby forming tight joints along the edges of the plate. The channels of the ledges F are preferably provided with projecting ribs, as shown in Fig. 5, to impinge against the front sides of the tubular packings.

I represents a groove which extends along the upper edge of the shield or plate E, opposite a rib or projecting bead, i, formed on the front wall, d, of the receiver, below the hinges e.

J is a packing of lead pipe, which is seated in the groove I and pressed against the rib z' when the plate E is closed down, thereby forming a tight joint along the upper edge of the plate. Vhen the plate E is swung down into position, its weight is sufficient to press the fillets of lead at #its upper end and sides against the projecting ridges h and z' with sufficient force to effect tight joints and prevent the escape of sewer-gas between its edges and the walls of the receiver. The plate E is held down in position by two rods or braces, l, which are pivoted at one end to the side walls of the trap and rest with their other ends against the rear side of the plate. 'Ihe opening of the sewer-pipe A is arranged at a suitable height above the bottom of the receiver B to retain a sufficient quantity of water in the receiver, and the lower end of the plate E is extended downward below the watenlevel a sufiicient distance to form a stench-trap. The length of the plate E is such that the plate can be swung upwardly in the receiver to expose the bottom of the receiver and the sewer-inlet without coming in contact with the rear wall of the receiver.

When it is desired to clean the bottom of the receiver, the cover C and grate c are removed, the rods or braces Z turned to-one side, and the plate E is swung upward upon its hinges, when the whole interior of the receiver is open and can be readily cleaned.

I claim as my invention- 1. The combination, with the receiver B,
